Right now I am exactly the same between the bg and the sensor. This one is proving to be pretty good and consistently close.tim2000s. I'm on day 6 of my first sensor and it is consistently running 1.5mmol lower (average) than my bg tests. I know Abbott say there can be a difference of 15%, but some of my results are as much as 30% out. May I ask how close your sensor readings and bg tests are as I'm disappointed with these results?
That's definitely one to get on the helpline and get replaced then.Thanks Tim. I've kept a record from day 1 and not one has been remotely close. The difference has been 16% to 35% lower every time ! At the moment I should be on the floor with a hypo as the sensor is telling me 3.2mmol, but I'm not as I know my bg is in fact 5.0mmol.
Very philosophical saying@June_C Don't take this wrong who's to say your meter is right? all meters have to be with in a certain %, what if the Libre is just reading slightly lower and your meter is just reading slightly higher?
a man with 1 watch knowns the time, a man with 2 watches is never quite sure..........

I appreciate your point, but when the sensor was telling me I was 2.3, when in fact I was 4.6, I had no doubt the sensor was wrong. It has been running between 25% - 35% lower than my bg and I've even been to the bother of comparing the two bg meters I have and they are only 0.1 to 0.2 different. Anyway, Abbott are sending me a replacement@June_C Don't take this wrong who's to say your meter is right? all meters have to be with in a certain %, what if the Libre is just reading slightly lower and your meter is just reading slightly higher?

I use the blood meter built into the libre, this was reading 5.8 coincidently my glucomen lx plus read exact the same as the libre blood reading so that was reassuring@Type1Bri Ahhh!....but what did your blood meter say it was?! lol
I'm different I'm afraid, I want to know what my bg is at any given time, I have to say the graphs are interesting, but as I say, not the reason for getting the Libre.This is correct.
The tolerance is about 15% for Libre and something similar for the BG meter. This means that with an *actual* BG of, say, 5.5, Libre could show 4.7 and meter 6.3 and both would still be "right".
Obviously for higher numbers, this gap gets bigger and bigger.
Personally, I find them reasonable close (for good numbers) generally, when I bother to check, but that Libre tends to read highs high and lows low (which I think is to do with the prediction algorithm it uses.
All these things are missing the point a bit for me, though - the real magic of the Libre is not the numbers, but the graphs you see afterwards - the line.
I have some strips on order that I can use with the Libre, so it'll be interesting to see how they compare with the sensor and my own bg meter (a glucomen lx plus like yours).Btw, what did the sensor tell you when you were 5.8?I use the blood meter built into the libre, this was reading 5.8 coincidently my glucomen lx plus read exact the same as the libre blood reading so that was reassuring
You may find the Libre is not for you. It doesn't tell you your BG level, at all. Full stop. It's also not a replacement for a bg tester, as it does lag your bg a bit (I tend to reckon by about ten minutes).I'm different I'm afraid, I want to know what my bg is at any given time, I have to say the graphs are interesting, but as I say, not the reason for getting the Libre.
